Benzocycle-substituted triazine and pyrimidine ultraviolet light absorbers

ABSTRACT

This invention relates generally to benzocycle-substituted pyrimidines and triazines and the use thereof to protect against degradation by environmental forces, inclusive of ultraviolet light, actinic radiation, oxidation, moisture, atmospheric pollutants and combinations thereof. The new class of benzocycle-substituted pyrimidines and triazines comprises a benzocycle attached to the triazine or pyrimidine ring, and preferably an additional aryl ring containing a hydroxyl group, either free or blocked to form a latent stabilizer, ortho- to the point of attachment to the triazine or pyrimidine ring. These materials may, under the appropriate circumstances, be bonded to formulations comprising coatings, polymers, resins, organic compounds and the like via reaction of the bondable functionality with the materials of the formulation. A method for stabilizing a material by incorporating such benzocycle-substituted pyrimidines and triazines is also disclosed.

BACKGROUND OF THE INVENTION

[0001] 1. Field of the Invention

[0002] This invention relates generally to novel benzocycle-substituted pyrimidines and triazines and their use as protectants against degradation by environmental forces, including ultraviolet light, actinic radiation, oxygen, moisture, atmospheric pollutants and combinations thereof.

[0003] 2. Description of Related Art

[0004] Exposure to sunlight and other sources of ultraviolet radiation is known to cause degradation of a variety of materials, especially polymeric materials. For example, polymeric materials such as plastics often discolor and may become brittle as a result of exposure to ultraviolet light. Accordingly, a large body of art has been developed directed towards materials such as ultraviolet light absorbers and stabilizers which are capable of inhibiting such degradation.

[0005] A class of materials known to be ultraviolet light absorbers are o-hydroxyphenyltriazines, in which at least one substituent on the 1, 3 or 5 carbon on the triazine ring is a phenyl group with a hydroxyl group ortho to the point of attachment to the triazine ring. In general this class of materials is well known in the art.

[0006] For example, U.S. Pat. No. 3,843,371 discloses hydroxyphenyltriazines for use in photographic materials. The triazines in this patent, however, show poor solubilities and poor stabilities.

[0007] U.S. Pat. No. 3,896,125 discloses hydroxyphenyl triazines, but these, too are poorly soluble and discolor with time.

[0008] The use of hydroxyphenyltriazines alone or in combination with other light stabilizers such as hydroxyphenylbenzotriazoles, benzophenones, oxanilides, cyanoacrylates, salicylates, and hindered amine light stabilizers (HALS), for the stabilization of polymers is also well known. For example, U.S. Pat. Nos. 4,853,471, 4,921,966, and 4,973,701, 4,973,702 disclose such combinations.

[0009] Typically, the aforementioned aryl ring with the hydroxyl group ortho to the point of attachment to the triazine ring is based on resorcinol and, consequently, this aryl ring also contains a second substituent (either a hydroxyl group or a derivative thereof) para- to the point of attachment to the triazine ring. For example, U.S. Pat. No. 3,118,837 and 3,244,708 disclose p-alkoxy-o-hydroxyphenyl triazines with improved UV protection, but many embodiments of such triazines exhibit poor compatibility and solubility, and poor yellowing performance.

[0010] This para- substituent can be “non-reactive,” as in the case of an alkyloxy group, or “reactive” as in the case of a hydroxyalkyloxy (active hydrogen reactive site) or (meth)acryloyl (ethylenic unsaturation reactive site) group. For the purposes of the present invention, the former are referred to as “non-bondable” benzocycle-substituted pyrimidines and triazines and the latter are referred to as “bondable” benzocycle-substituted pyrimidines and triazines.

[0011] Low volatility is an important characteristic of stabilizers used in any applications where high temperatures are encountered. High temperatures are used in the processing of tnermoplastics and in the curing of thermoset resins and coatings. High temperatures are also often present in the end-use applications for the stabilized material. Low volatility will prevent loss of the stabilizer during processing, curing, and high temperature end-uses. Besides reducing losses of stabilizer during processing or curing, low volatility will minimize processing problems such as die lip build-up and plate-out.

[0012] Many polymer additives (such as ultraviolet light stabilizers) migrate out of the polymer substrate to be protected, or are adsorbed (chemically or physically) by one or more systems components (such as pigments), thereby diminishing their effectiveness. Such migration and adsorption problems are examples of the general problems of lack of solubility and compatibility found for many commercial polymer additives.

[0013] Bondable triazines are well known in the art. For example, U.S. Pat. Nos. 3,423,360, 4,962,142 and 5,189,084 disclose various bondable and the incorporation of these compounds into polymers by chemical bonding. Bondable stabilizers have a potential advantage in this respect in that, depending on the bondable functionality and the particular polymer system to be stabilized, they can be chemically incorporated into a polymer structure via reaction of the bondable functionality either during polymer formation (such as in the case of polymerizing monomers or a crosslinking polymer system) or subsequently with a preformed polymer having appropriate reactive functionality. Accordingly, due to such bonding, migration of these UV absorbers between layers of multi-layer coatings and into polymer substrates is greatly reduced.

SUMMARY OF THE INVENTION

[0014] The present invention provides a new class of benzocycle-substituted pyrimidines and triazines depicted below, in which a substituent attached to the triazine or pyrimidine ring is a fused benzocyclic group:

[0015] wherein X signifies hydrogen or a blocking group, A can be a nitrogen or optionally substituted methine, and the fused ring designated by S is a non-aromatic 4 to 12 membered ring, optionally containing one or more heteroatoms; any of the three rings may bear one or more additional substituents. These fused benzocyclic-substituted triazines and pyrimidines have the advantage of being highly soluble in and compatible; of having extremely low volatility, and therefore low losses during high temperature processing or curing; of being highly effective in inhibiting yellowing; and of being highly effective in preventing degradation of polymers and coatings due to the action of actinic radiation, heat, oxygen, and moisture.

[0016] The benzocyclic substituted triazine and pyrimidine UV absorbers of the present invention possess exceptionally low volatility, lower than most current art UV absorbers. Furthermore these benzocyclic triazine UV absorbers, impart improved weatherability and yellowing resistance to polymers compared to current art UV absorbers. None of the previously available triazine UV stabilizers and absorbers combine the unexpected low volatility along with the weatherability, yellowing resistance, solubility, and compatibility of the benzocyclic substituted triazine and pyrimidine absorbers and stabilizers of the present invention.

[0161] The benzocycle-substituted pyrimidines and triazines of the present invention may optionally have the added benefit of being capable of being chemically bonded to appropriate polymer systems via functionality attached to the benzocycle, pyrimidine and triazine groups (e.g., by a hydroxyl, ethylenic unsaturated and/or activated unsaturated group in one or more of R¹, R², Y or Z).

[0162] These benzocycle-substituted pyrimidines and triazines may in general be prepared via a number of procedures well known in the art, for example, those described in Brunetti, H; Luethi, C.; Helv. Chemica Acta, 55 (1972) pp. 1566-1595; Tanimoto, S.; Yamagata, M. Senryo to Yakahin, 40 (1995) pp 339ff; U.S. Pat. Nos. 5,106,972, 5,288,868, 5,438,138, and 5,478,935; EP 395,938; EP 577,559; EP 649,841; EP 779,280; WO 9,628,431; GB 884,802; and Japanese Patent Kokai Tokkyo Koho 9,059,263 all of which are incorporated herein by reference for all purposes as if fully set forth.

[0163] The novel benzocycle-substituted pyrimidines and triazines of the present invention are particularly useful as ultraviolet light absorber agents for stabilizing a wide variety of materials including, for example, organic compounds, oils, fats, waxes, cosmetics, dyes and biocides, and particularly various organic polymers (both crosslinked and non-crosslinked) used in applications such as photographic materials, plastics, fibers or dyed fibers, rubbers, paints and other coatings, and adhesives. The present invention, consequently, also relates to (1) a method of stabilizing a material which is subject to degradation by actinic radiation (e.g., an organic material such as an organic polymer in the form of a film, fiber, shaped article or coating) by incorporating into said material an amount of an actinic radiation stabilizer composition effective to stabilize the material against the effects of actinic radiation, wherein the actinic radiation stabilizer composition comprises the inventive benzocycle-substituted 1,3,5-triazine or pyrimidine; and (2) the material so stabilized.

[0164] The novel benzocycle-substituted pyrimidines and triazines of the present invention are also effective as ultraviolet light screening agents in applications such as sunscreens and other cosmetic preparations, capstock layers for extruded polymers, dyed fibers and laminated UV-screening window films, among others. The present invention, consequently, also relates (1) to a method of protecting a substrate against degradation by actinic radiation by applying to the substrate an actinic radiation screening layer (e.g., a coating film or capstock layer) containing an actinic radiation screening composition in an amount effective to reduce the amount of actinic radiation impinging on the substrate, wherein the actinic radiation screening composition comprises the inventive benzocycle-substituted pyrimidines and triazines; and (2) the substrate so protected.

[0165] The novel benzocycle-substituted pyrimidines and triazines of the present invention may also be employed to form light stabilizing compositions. Such light stabilizing compositions may include a variety of other components known in the art including other ultraviolet light absorbers of the triazine class, other ultraviolet light absorbers of different classes (e.g. benzotriazoles, benzophenones), hindered amine light stabilizers, radical scavengers, antioxidants and the like.

[0166] These and other features and advantages of the present invention will be more readily understood by those of ordinary skill in the art from a reading of the following detailed description.

DETAILED DESCRIPTION OF THE PREFERRED EMBODIMENTS The Benzocycle-substituted Pyrimidines and Triazines

[0167] As used herein, the term “benzocycle-substituted pyrimidines and triazines” broadly refers to any compound of formulas (I) through (IX), above.

[0168] As used herein, the term “benzocycle” broadly refers to any compound or substituent of general formula (X):

[0169] Wherein substituents G, R¹, R², and subscripts m, n, o, p, and q, are defined as above for general formulas (I), (II), (III), and (IV);

[0170] The term “hydrocarbyl” in the context of the present invention, and in the above formulas, broadly refers to a monovalent hydrocarbon group in which the valency is derived by abstraction of a hydrogen from a carbon atom. Hydrocarbyl includes, for example, aliphatics (straight and branched chain), cycloaliphatics, aromatics and mixed character groups (e.g., aralkyl and alkaryl). Hydrocarbyl also includes such groups with internal unsaturation and activated unsaturation. More specifically, hydrocarbyl includes (but is not limited to) such groups as alkyl, cycloalkyl, aryl, aralkyl, alkaryl, alkenyl, cycloalkenyl and alkynyl, preferably having up to 24 carbon atoms. A hydrocarbyl may optionally contain a carbonyl group or groups (which is/are included in the carbon count) and/or a heteroatom or heteroatoms (such as at least one oxygen, sulfur, nitrogen or silicon), in the chain or ring.

[0171] The term “functional hydrocarbyl” in the context of the present invention, and in the above formulas, broadly refers to a hydrocarbyl possessing pendant and/or terminal reactive and/or latent reactive functionality and/or leaving groups. “Reactive” functionality refers to functionality which is reactive with common monomer/polymer functionality under normal conditions well understood by those persons of ordinary skill in the relevant art. As non-limiting examples of reactive functionality may be mentioned active hydrogen-containing groups such as hydroxyl, amino, carboxyl, thio, amido, carbamoyl and activated methylene; isocyanato; cyano; epoxy; ethylenically unsaturated groups such as allyl and methallyl; and activated unsaturated groups such acryloyl and methacryloyl, and maleate and maleimido (including the Diels-Alder adducts thereof with dienes such as butadiene). “Latent reactive” functionality within the meaning of the present invention and, as would clearly be understood by those persons of ordinary skill in the art, refers to reactive functionality which is blocked or masked to prevent premature reaction. As examples of latent reactive functionality may be mentioned ketimines and aldimines (amines blocked, respectively, with ketones and aldehydes); amine-carboxylate salts; and blocked isocyanates such as alcohol (carbamates), oxime and caprolactam blocked variations. A “leaving” group within the meaning of the present invention, as would clearly be understood by those persons of ordinary skill in the relevant art, is a substituent attached to the hydrocarbyl chain or ring which during reaction is dislodged or displaced to create a valency on a carbon or heteroatom in the hydrocarbyl chain or ring, said valency being filled by a nucleophile. As examples of leaving groups may be mentioned halogen atoms such as chlorine, bromine and iodine; hydroxyl groups (protonated and unprotonated); quaternary ammonium salts (NT₄ ⁺); sulfonium salts (ST₃ ⁺); and sulfonates (—OSO₃T); where T is, e.g., methyl or para-tolyl. Of all these classes of reactive functionality, the preferred functionality includes hydroxyl, —COOR⁵, CR⁶═CH₂, —CO—CR⁶═CH₂, Cl, an isocyanate group, a blocked isocyanate group and —NHR⁵, wherein

[0172] R⁵ is selected from hydrogen and a hydrocarbyl (preferably of up to 24 carbon atoms); and

[0173] R⁶ is selected from hydrogen and an alkyl of 1 to 4 carbon atoms (preferably hydrogen and methyl).

[0174] The term “hydrocarbylene” in the context of the present invention is a divalent hydrocarbon group in which both valencies derive by abstraction of hydrogens from carbon atoms. Included within the definition of hydrocarbylene are the same groups as indicated above for hydrocarbyl and functional hydrocarbyl with, of course, the extra valency (for example, alkylene, alkenylene, arylene, alkylaryl, etc.).

[0175] The term “functional hydrocarbylene” in the context of the present invention refers to a species of hydrocarbylene possessing pendant reactive functionality, latent reactive functionality and/or leaving groups. The term “non-functional hydrocarbylene” in the context of the present invention refers generally to a hydrocarbylene other than a functional hydrocarbylene.

[0176] The benzocycle-substituted pyrimidines and triazines in accordance with the present invention also relate to latent stabilizing compounds against actinic radiation of the general formulas (I), (III), and (IV), wherein at least one of the hydroxyl groups on an aryl ring ortho to the point of attachment to the triazine or pyrimidine ring is blocked, that is, wherein at least one X is other than hydrogen. Such latent stabilizing compounds liberate the effective stabilizers by cleavage of the O—X bond, e.g., by heating or by exposure to UV radiation. Latent stabilizing compounds are desirable because they have many favorable properties, i.e., good substrate compatibility, good color properties, a high cleavage rate of the O—X bond and a long shelf life. The use of latent stabilizing compounds is further described in U.S. Pat. Nos. 4,775,707, 5,030,731, 5,563,224 and 5,597,854, which are incorporated herein for all purposes as if fully set forth.

[0177] Latent stabilizing compounds comprising the benzocycle-substituted pyrimidines and triazines in accordance with the present invention can be prepared from compounds of the general formulas (I), (II) and (IV) through (IX), wherein at least one X is hydrogen, by subjecting said compounds to a further reaction to form latent stabilizing compounds, as described in the immediately preceding incorporated references.

[0178] As preferred examples of blocking groups X may be mentioned one or more of the following groups: allyl, —COR^(a), —SO₂R^(b), —SiR^(c)R^(d)R^(e), —PR^(f)R^(g) or —POR^(f)R^(g), —CONHR^(h),

[0180] each R^(a) is independently selected from C₁-C₈ alkyl, halogen-substituted C₁-C₈ alkyl, C₅-C₁₂ cycloalkyl, C₂-C₈ alkenyl, —CH₂—CO—CH₃, C₁-C₁₂ alkoxy, and phenyl or phenoxy which is unsubstituted or substituted by C₁-C₁₂ alkyl, C₁-C₄ alkoxy, halogen and/or benzyl;

[0183] each R^(f) and R^(g) is independently selected from C₁-C₁₂ alkoxy, C₁-C₁₂ alkyl, C₅-C₁₂ cycloalkyl, and phenyl or phenoxy which is unsubstituted or substituted by C₁-C₁₂ alkyl, C₁-C₄ alkoxy, halogen and/or benzyl; and

The reaction to give the latent stabilizing compounds of the present invention of the general formulas (III) through (X) in which X is —CONHR^(h) can be carried out, for example, by reaction of the compounds of the general formulas (III) through (X), wherein at least one X is hydrogen with the corresponding isocyanates. Furthermore, acylated compounds can be obtained by reaction with anhydrides, ketenes or esters, such as lower alkyl esters, as is well known to one skilled in the art. The above-described reagents may be used in approximately equimolar amounts or in excess, for example, from 2 to 20 mol with respect to the hydroxyl groups desired to be made latent in the starting compound of the general formula (I), (III), or (IV).

[0186] Catalysts customarily used for acylation, sulfonylation, phosphonylation, silylation or urethanation reactions may be used in forming the latent stabilizing benzocycle-substituted pyrimidines and triazines of the present invention. For example, acylation and sulfonylation reaction catalysts such as tertiary or quaternary amines, such as triethylamine, dimethylaminopyridine or tetrabutylammonium salts, may be used for forming these latent stabilizing compounds.

[0187] The reaction may be carried out in the presence of a solvent, such as relatively inert organics, e.g., hydrocarbons such as toluene and xylene, chlorinated hydrocarbons such as carbon tetrachloride or chloroform, or ethers such as tetrahydrofuran or dibutyl ether, or without a solvent. Alternatively, the reagent(s) may be employed as the solvent. The reaction temperature is usually between room temperature and about 150° C., for example, up to the boiling point of the solvent when a solvent is used.

[0214] As used herein, the term “step-wise” means a reaction sequence wherein a series of reactions are conducted, the first reaction producing compounds of Formulas (XXXII), (XXXV), or (XXXVI) and being carried out to between about 50% to about 100% completion prior to addition of a compound of Formula (XXXIII) to produce compounds of Formulas (I), (IV a/b/c), or (V). Preferably the reaction is carried out to between about 70% to about 100% completion prior to addition of compound of Formula (XXXIII), and more preferably to between about 75% to about 100% completion.

[0216] The novel benzocycle-substituted pyrimidines and triazines of the present invention can be prepared through the Friedel-Crafts reaction of a benzocycle moiety (XXX) with a halogen-substituted pyrimidine or triazine compound of Formula (XXXI) or (XXXIV). See Schemes 1, 2, and 3.

[0217] wherein Hal is bromine, chlorine, or iodine. Compound (XXX) is defined as a protonated compound of Formula (X), as defined above.

The amount of acid used in the reaction should be in sufficient amounts to transform 2,4,6-trihalo-1,3,5-triazine or 2,4,6-trihalopyrimidine to the preferred 2-halo-4,6-bisbenzocyclic-1,3,5-triazine or 2-halo-4,6-bisbenzocyclicpyrimidine, respectively, or convert 2-halo-4,6-bisbenzocyclic-1,3,5-triazine or 2-halo-4,6-bisbenzocyclicpyrimidine to the compounds of Formula (I), (IV a/b/c), or (V), as desired. Preferably, the amount of acid should be between about 0.01 mol to about 5 mol equivalents.

[0222] For all synthetic schemes, the Lewis acid and acid preferably combine to form a mixture that can be prepared in situ or pre-formed prior to addition to the reagents. The Lewis acid and/or acid can be combined with either the benzocyclic compound of Formula (XXX), compounds of Formula (XXXI) or (XXXIV), or both, in any manner. In situ reaction mixture preparation comprises addition of at least one Lewis acid and at least one acid to at least one compound of Formula (XXXI) or (XXXIV), at least one benzocyclic compound of Formula (XXX), and optionally solvent, without regard to addition order. To prepare the mixture prior to addition to the reagents, i.e., the pre-formed method, at least one Lewis acid and at least one acid are combined and allowed to mix prior to addition, optionally in an inert solvent. Thereafter, the mixture is added to the reagents or vice versa, as desired and in any addition order. As used herein, one or more Lewis acids may be used, the first step and the second step Lewis acid may be the same or different. Additionally, one or more acids may be used, the first step and second step acid may be the same or different. In the “continuous” process, the use of additional Lewis acid, acid, or both is optional.

[0223] If the complex is prepared using the pre-formed method, preferred mixing time of the Lewis acid and acid, prior to addition to the reagents, is between about 1 minute to about 5 hours, more preferred time is between about 10 minutes to about 2 hours.

The preferred reaction temperature for the second step is between about 0° C. and about 120° C., a more preferred reaction temperature is between about 20° C. and about 100° C.

[0225] The step-wise process comprises mixing at least one Lewis acid, at least one acid, and compounds of Formula (XXXI) or (XXXIV) with one or more of the desired benzocyclic compounds of Formula (XXX), preferably until the reaction is between about 70% to about 100% completed. Thereafter, the product is isolated and purified. The aromatic compound of Formula (XXXIII) is added to the purified product along with Lewis acid and optionally an acid to synthesize the compounds of Formula (I), (IV a/b/c), or (V). The step-wise sequence allows for the isolation, purification, and storage of compounds of Formula (XXXII), (XXXV), or (XXXVI) prior to subsequent reaction with aromatic compounds of Formula (XXXIII).

[0226] The continuous reaction comprises allowing a compound of Formula (XXXI) or (XXXIV) to react with one or more benzocyclic compounds of Formula (XXX) in the presence of at least one Lewis acid and at least one acid preferably until the reaction is between about 70% to about 100% complete. Thereafter, without isolating the product of Formula (XXXII), (XXXV), or (XXXVI), the aromatic compound of Formula (XXXIII) is allowed to react with the product of Formula (XXXII), (XXXV), or (XXXVI) in the presence of optionally at least one second Lewis acid and optionally at least one second acid preferably until the reaction is between about 70% to about 100% complete. The continuous reaction eliminates the need to purify the intermediate product of Formula (XXXII), (XXXV), or (XXXVI) or use of additional reagents such as solvents, and optionally Lewis acids and acids. Moreover, the one-step process simplifies the synthetic reaction pathway such that no unnecessary handling or processing of the reaction mixture is required until the reaction is completed.

The addition temperature of the aromatic compound of Formula (XXXIII) to the reaction mixture is between about 0° C. to about 150° C., preferred addition temperature is between about 20° C. to about 100° C.

[0230] The Lewis acid/acid mixture should be present in amounts sufficient to react with the number of halogens being substituted on compounds of Formula (XXXI) or (XXXIV). A range of between about 1 to about 5 mol equivalents of Lewis acid and a range of between about 0.01 mol to about 5 mol equivalents of acid can be used. The preferred Lewis acid is aluminum chloride. A preferred amount of Lewis acid is between about 2 to about 4 mol equivalents to halo-triazine or halo-pyrimidine. A preferred amount of acid is between about 0.05 mol to about 2 mol equivalents to compounds of Formula (XXXI) or (XXXIV).

[0231] The synthesis of compounds of Formula (VI), (VII), VIII), or (IX) can be performed by methods commonly known in the art. One of ordinary skill in the art with little or no experimentation can determine the appropriate conditions to obtain the polymer product desired.

ALIPHATIC POLYAMIDE

[0277] The novel benzocyclie-substituted pyrimidines and triazines of the present invention can also be used with aliphatic polyamide polymers. An “Aliphatic polyamide” is a polyamide characterized by the presence of recurring carbonamide groups as an integral part of the polymer chain which are separated from one another by at least two aliphatic carbon atoms. Illustrative of these polyamides are those having recurring monomeric units represented by the general formula:

—NHC(O)RC(O)NHR¹— or —NH—R—C(O)—

[0278] or a combination hereof in which R and R¹ are the same or different and are alkylene groups of at least about two carbon atoms, preferably alkylene having from about 2 to about 12 carbon atoms. Exemplary of such polyamides are polyamides formed by the reaction of diamines and diacids such as poly (tetramethylene adipamide)(nylon 4,6); poly(hexamethylene adipamide) (nylon 6,6); poly (hexamethylene azelamide) (nylon 6,9); poly(hexamethylene sebacamide) (nylon 6,10); poly(heptamethylene pimelamide) (nylon 8,8); poly(nonamethylene azelamide) (nylon 9,9); poly(decamethylene azelamide) (nylon 10,9); and the like. Also illustrative of useful aliphatic polyamides are those formed by polymerization of amino acids and derivatives thereof, as for example lactams. Illustrative of these useful polyamides are poly(4-aminobutyric acid) (nylon 4); poly(6-aminohexanoic acid) (nylon 6); poly(7-aminoheptanoic acid) (nylon 7); poly(8-aminoocatanoic acid) (nylon 8); poly(9aminononanoic acid) (nylon 9); poly(10-aminodecanoic acid) (nylon 10); poly(11-aminoundecanoic acid) (nylon 11); poly(12-aminododecanoic acid) (nylon 12); and the like. Blends of two or more aliphatic polyamides may also be employed.

[0279] Copolymers formed from any combination of the recurring units of the above referenced aliphatic polyamides can be used. By way of illustration and not limitation, such aliphatic polyamide copolymers include caprolactam/hexamethylene adipamide copolymer (nylon 6/6,6); hexamethylene adipamide/caprolactam copolymer (nylon 6, 6/6); hexamethylene adipamide/hexamethylene-azelamide copolymer (nylon 6,6/6,9); and copolymers formed from recurring units of the above referenced aliphatic polyamides with aliphatic/aromatic polyamide recurring units may also be used. Examples of such copolyamides are nylon 6/6T; nylon 6,6/6, T; nylon 6/10T; nylon 6/12T; nylon 6,10/6,T etc.

[0280] Preferred aliphatic polyamides for use in the practice of this invention are poly(caprolactam); poly(7-aminoheptanic acid); poly(tetramethylene adipamide); poly(hexamethylene adipamide); and mixtures thereof. The particularly preferred aliphatic polyamides are poly(caprolatam); poly(hexamethylene adipamide); poly(tetramethylene adipamide); and mixtures thereof.

[0281] Aliphatic polyamides useful in the practice of this invention may be obtained from commercial sources or prepared in accordance with known preparatory techniques. For example, polycaprolactam may be obtained from Allied Signal Inc. and poly(hexamethylene adipamide) may be obtained from DuPont Co.

[0282] The number average molecular weight of the aliphatic polyamide may vary widely. Usually, the aliphatic polyamide is of film forming molecular weight that is sufficiently high to form a free standing film and sufficiently low to allow melt processing of the blend into a film. Such number average molecular weights are well known to those of skill in the film art and are usually at least about 5,000 as determined by the formic acid viscosity method. In this method, a solution of 9.2 wt. Concentration of aliphatic polyamide in 90% formic acid at 25° C. is used. In the preferred embodiments of the invention, the number average molecular weight of the aliphatic polyamide is from about 5,000 to about 1,000,000 and in the particularly preferred embodiments is from about 10,000 to about 100,000. Amongst the particularly preferred embodiments, most preferred are those in which the molecular weight of the aliphatic polyamide is from about 20,000 to about 40,000.

POLYURETHANE

[0283] Polyurethane (PUR) elastomer products (“spandex”) can be stabilized against discoloration and loss of elasticity during UV light exposure with combinations of UV absorbers according to the invention and hindered amine light stabilizers. Spandex fibers is a PUR elastomer product, which requires very specific UV absorber and hindered amine light stabilizers properties in order to achieve optimum performance. UV absorbers of the triazine class of this invention can be combined with polymeric hindered amine light stabilizers (HALS) to provide outstanding performance in achieving the desired properties for the Spandex fiber applications.

[0284] The triazine UV absorber of the invention, used alone or in combination with HALS provides the following properties in the Spandex fiber application: (1) low color contribution at typical use levels in the 0.5-2.0% range; (2) sufficient MW, thermal stability and low volatility for fiber processing and thermal exposure conditions; (3) high compatibility and permanence; (4) prevent discoloration and loss of elasticity during exposure to UV light energy; (5) low extraction by water and dry cleaning solvents; (6) low color development during exposure to atmospheric pollutants, NO_(x), SO_(x), hydrocarbons, etc.; (7) low interaction with sea water and pool chemicals; (8) low interaction and color development with typical phenolic antioxidants used for the thermal stabilization of Spandex fibers; and (9) low interaction with copper based antioxidant systems used in Nylon fibers for Nylon/Spandex fabrics.

[0285] The triazine UV absorber with or without the polymeric HALS provides outstanding stabilization with minimum negative effect on secondary performance properties, such as low color development during NO_(x) exposure and low interaction with copper based antioxidant systems using in Nylon fibers.

[0286] As noted above, any of the triazine compounds disclosed herein can be used to impart one or more of the properties described above to Spandex fibers when added thereto in a stabilization effective amount.

[0287] Preferably, these triazine compounds are added in combination with polymeric HALS. The polymeric HALS is preferably poly[(6-morpholino-s-triazine-2,4-diyl)[2,2,6,6,-tetramethyl-4-piperidyl)imino]-hexamethylene [(2,2,6,6-tetramethyl-4-piperidyl)imino]]. Most preferably, the polymeric HALS is the methylated (M) version of the above HALS, which is sold by Cytec Industries, Inc. as CYASORB®UV-3529 light stabilizer. Other polymeric HALS disclosed in U.S. Pat. No. 4,331,586 are also suitable.

[0288] Spandex fibers are made from a polyurethane (PUR) prepolymer prepared from a diisocyanate and a glycol. There are four basic processes used to convert the PUR prepolymer into the fiber product. These processes are Solution Dry Spinning, Solution Wet Spinning, Melt Extrusion, and Reaction Spinning. The above UV stabilizer alone or in combination with HALS would be suitable for use in any or all four processes.

[0289] Spandex fibers may contain a processing antioxidant system, such as a phenolic antioxidant, or a phenolic/phosphite antioxidant combination. In addition, pigments, such as TiO₂ are commonly used in the fiber products.

[0290] The triazine UV absorber alone or with M-HALS can be dissolved into DMF or DMAC and added to the PUR prepolymer solution prior to solution fiber spinning processes. Also, the combination can be extrusion compounded into the PUR compound used in the melt spinning process.

POLYCARBONATES

[0291] Among polymeric materials to be stabilized with the novel benzocycle-substituted pyrimidines and triazines of the present invention, preference is given to the polycarbonates, polyesters, polyamides, polyacetals, polyphenylene oxides and polyphenylene sulfides, but especially to the polycarbonates. Those compounds are to be understood as being especially those polymers the constitutional repeating unit of which corresponds to the formula:

[0292] wherein A is a divalent phenolic radical. Examples of A are given inter alia in U.S. Pat. No. 4,960,863 and

[0293] DE-A-3 922,496. A can be derived, for example, from hydroquinone, resorcinol, dihydroxybiphenylene or bisphenols in the broadest sense of the term, such as bis(hydroxyphenyl)alkanes, cycloalkanes, sulfides, ethers, ketones, sulfones, sulfoxides, α,α′-bis(hydroxyphenyl)-diisopropylbenzenes, for example the compounds 2,2-bis(4-hydroxyphenyl)propane, 2,2-bis(3,5-dimethyl-4-hydroxyphenyl)-propane, 2,2-bis(3,5-dichloro-4-hydroxyphenyl)propane, 1,1-bis(4-hydroxyphenyl)cyclohexane, or from the compounds of the formulae:

[0294] In one embodiment, the preferred resins are polycarbonates based on dihydric phenols such as 2,2-bis-(4-hydroxyphenyl)propane (bisphenol A); 2,4-bis (4-hydroxyphenyl)-2-methylbutane; 1,1-bis-(4-hydroxyphenyl)-cyclohexane; 2,2-bis-(3-chloro-4-hydroxyphenyl)propane; 4,4′-sulfonyldiphenol; and 1,1-bis-(4-hydroxyphenyl)-3,3,5-trimethylcyclohexane.

[0295] Also preferred are polycarbonate copolymers incorporating two or more phenols, branched polycarbonates wherein a polyfunctional aromatic compounds is reacted with the dihydric phenol(s) and carbonate precursor, and polymer blends of which polycarbonate comprises a significant portion of the blend.

[0296] The most preferred resins for both layers are polycarbonates based on bisphenol A.

[0297] U.S. Pat. No. 5,288,788 also describes polycarbonates and polyester carbonates, especially aromatic polycarbonates, for example those based on 2,2-bis(4-hydroxyphenyl)propane or 1,1-bis(4-hydroxyphenyl)cyclohexane.

MULTILAYER SYSTEMS

[0298] British Patent Application No. 2,290,745 describes a number of methods have been developed to concentrate UV absorbers near or at the surface of polymeric materials. These include surface impregnation (see U.S. Pat. Nos. 3,309,220, 3,043,709, 4,481,664 and 4,937,026) and coating a plastic article with solutions containing thermoplastic resins and UV absorbers (see U.S. Pat. Nos. 4,668,588 and 4,353,965). Both techniques suffer from drawbacks including requiring additional processing steps (i.e. applying, drying or curing), and encounter difficulties associated with the handling of large processed articles. An additional drawback, particularly relevant to polycarbonate sheet production, is the detrimental effect such post addition treatment would have on the surface of the polymeric substrate.

[0299] As described in the U.S. Pat. No. 5,445,872, application of surface layers via coextrusion takes place in a known manner in known coextrusion equipment as taught in U.S. Pat. Nos. 3,487,505 and 3,557,265. Coextrusion is a well recognized method of producing laminated thermoplastic materials by simultaneously extruding various numbers of layers which form a single composite material. U.S. Pat. No. 4,540,623 describes coextruded materials of at least forty layers. Other methods produce as few as two or three different layers.

[0300] In one embodiment, the invention also relates to thermoplastic articles coated with a thermoplastic layer 0.1 to 10 mil (0.00254 mm to 0.254 mm), preferable 0.1 to 5 mil (0.00254 mm to 0.127 mm), thick, in which said layer contains 0.1% to 20% by weight of the benzocyclie-substituted pyrimidines and triazines of the present invention. Preferred concentrations of are 2% to 15% by weight; most preferred concentrations of 5% to 10% by weight.

[0301] The benzocycle-substituted pyrimidines and triazines of the present invention may be incorporated into the thermoplastics of the surfaces layer by standard methods such as dry mixing the additives with granular resin prior to extruding.

[0302] The benzocycle-substituted pyrimidine or triazine layer may be applied to one or both sides of the thermoplastic article.

[0303] Laminated thermoplastic articles which contain additional layers such as a water resistant layer as found in U.S. Pat. No. 4,992,322 are also part of the present invention.

[0304] The core layer and the coating layer may be the same or different thermoplastic resin including polyesters, polyester carbonates, polyphenylene oxide, polyvinyl chloride, polypropylene, polypropylene, polyethylene, polyacrylates, polymethacrylates and copolymers and blends such as styrene and acrylonitrile on polybutadiene and styrene with maleic anhydride, and mixtures (polyblends) of such polymers with one another or with other polymers, for example with polyolefins, polyacrylates, polydienes or other elastomers in the form of impact strength modifiers.

BONDABLE STABILIZERS

[0305] The benzocycle-substituted pyrimidines and triazines of the present invention can also be chemically bonded to substrates, such as polymers, thereby greatly reducing the migration of such UV absorbers, e.g., out of the substrate or away from the substrate surface. The bonding mechanism of the triazines of the present invention involves the formation of a bond (chemical and/or co-valent) between a functionality attached to the amido or carbamate group, e.g., by a pendant vinyl or hydroxyl group, and the “host” substrate, such as a polymer.

[0306] Incorporation of the benzocycle-substituted pyrimidines and triazines of the invention can be brought about by copolymerization, copolyaddition, copolycondensation, by reaction with a polymer which carries suitable functional groups, or by grafting, in a manner as disclosed in U.S. Pat. Nos. 3,423,360 and 5,189,084 which are incorporated herein by reference as if filly set forth.

[0307] Bonding of the benzocycle-substituted pyrimidines and triazines of the invention can occur by polymerization or copolymerization. In the case of the novel triazines of the present invention comprising pendant vinyl groups, polymerization or copolymerization with at least one vinyl monomer, e.g., (meth)acrylic acid, esters of (meth)acrylic acid such as methyl acrylate, amides of (meth)acrylic acid, hydroxyethylacrylate, olefins, vinyl chloride, styrene, butadiene, isoprene and acrylonitrile can be carried out to form homopolymers or copolymers in which the vinyl group is incorporated into the backbone of the polymer. Polymerization or copolymerization can be initiated by initiators, such as free radical, anionic and cationic types, or by actinic radiation, such as UV, electron beam, x-rays and gamma irradiation from a Co⁶⁰ source, as is well known to those in the polymerization art. Polymerization or copolymerization can be carried out in solution, in an emulsion, in a dispersion, in the melt, or in the solid state as is well known to those in the polymerization art.

[0308] Also, bonding of the presently claimed benzocycle-substituted pyrimidines and triazines compounds of the present invention can be brought about by copolyaddition or copolycondensation. Such incorporation can be made by addition during the synthesis of an addition polymer or copolymer or by condensation during the synthesis of a condensation polymer or copolymer by methods known to those skilled in the art. For example, compounds of the formula (I), (II), or (IV)-(IX) containing the appropriate functional groups can be incorporated into polyesters, polyamides, polyurethanes, epoxy resins, melamine resins, alkyd resins, phenolic resins, polyurethanes, polycarbonates, polysiloxanes, polyacetals and polyanhydrides, to name but a few.

[0309] In addition, compounds of the formula (I), (II), or (IV)-(IX) can be bonded to a monomeric component which is then incorporated into a polymer or copolymer, e.g., by the free radical initiated addition or copolycondensation methods described above. Analogous methods are disclosed in, for example, U.S. Pat. No. 5,459,222 (incorporated by reference herein for all purposes as if fully set forth) for the bonding of benzotriazole and benzophenone stabilizers to diol precursors which are then incorporated by condensation polymerization into polyurethanes and polyesters to impart UV stabilizing properties to said polymers.

[0310] Alternately, the benzocycle-substituted pyrimidines and triazines of the invention may also be bonded to polymers by reaction with an oligomer and/or polymer which carries suitable functional groups. For example, at least one triazine compound comprising a vinyl pendant group can be added, optionally with at least one other vinyl monomer or compound comprising -a vinyl group, to unsaturated polyester resins, unsaturated polybutadiene oligomers or unsaturated rubbers and then cured by actinic radiation or by a free radical catalyst. Or, at least one triazine compound comprising a terminal functional group, such as hydroxyl or amido, may be reacted with a polymer and/or oligomer such as polyesters, polyurethanes and polydiols with reactive end-groups, partially hydrolyzed polyvinylacetate, epoxy resins, polysiloxanes and polymers comprising maleic anhydride, either in the main chain or as a side-chain, by methods analogous to those well known to those of ordinary skill in the art.

[0311] Grafting is yet another way of bonding of the presently claimed benzocycle-substituted pyrimidines and triazines to polymers and/or oligomers. Grafting may be carried out in solution, in the melt, or in the solid state with the initiators or actinic radiation types discussed above for polymerization when, for example, the novel triazines of the present invention comprising pendant vinyl groups are used. Such benzocycle-substituted pyrimidines and triazines may be grafted to saturated polymers, e.g., polyolefins and their copolymers such as polyethylene, polypropylene and poly(ethylene-vinyl acetate), or to polymers comprising unsaturated moieties, e.g., polybutadiene, polyisoprene, ethylene-propylene-(diene monomer) terpolymers and polystyrene and its copolymers.

[0312] The benzocycle-substituted pyrimidines and triazines of the present invention may be used in widely varying amounts in such applications depending upon such things as the material to be stabilized and the particular application. However, when employed as a stabilizing additive for materials such as organic polymers, the benzocycle-substituted pyrimidines and triazines of the present invention are typically employed in amounts from about 0.01 to about 20% by weight, preferably from about 0.1 to about 10% by weight, and most preferably from about 0.1 to about 5% by weight, based on the weight of the material to be stabilized. In screening applications such as sunscreening compositions, the triazines are utilized in the same relative amounts but based on the total weight of the screening agent.

[0313] The novel stabilizers of the present invention may also be employed in a non-bondable capacity, for example, in the stabilization of thermoplastic polymers as set forth in the many of the previously incorporated references. Examples of preferred thermoplastic polymers are polyolefins and polymers comprising heteroatoms in the main chain. Preferred polymers are also thermoplastic polymers comprising nitrogen, oxygen and/or sulphur, especially nitrogen or oxygen, in the main chain. Also of interest are compositions in which the polymer is a polyolefin, for example polyethylene or polypropylene.

[0314] Incorporation into the thermoplastic polymers can be carried out by addition of the novel benzocycle-substituted triazine or pyrimidine compound and any further additives by the methods conventional in the art. The incorporation can expediently be made before or during shaping, for example by mixing the pulverulent components or by adding the stabilizer to the melt or solution of the polymer, or by applying the dissolved or dispersed compounds to the polymer, with or without subsequent evaporation of the solvent. Elastomers can also be stabilized as lattices.

[0315] The novel mixtures can also be added to the polymers to be stabilized in the form of a masterbatch which comprises these compounds, for example, in a concentration of from about 2.5 to about 25%, preferably from about 5 to about 20% by weight of the polymer.

[0316] The novel mixtures can expediently be incorporated into the polymeric material by any number of methods, including those conventionally employed in the art, including by, for example: a) as an emulsion or dispersion (for example to lattices or emulsion polymers); (b) as a dry mix during mixing of additional components or polymer mixtures; (c) by direct addition to the processing equipment (for example extruders, internal mixers, etc.); or (d) as a solution or melt.

[0317] The stabilized polymer compositions obtained in this way can be converted into shaped articles, for example fibers, films, tapes, sheets, sandwich boards, containers, pipes and other profiles, by any number of conventional methods, for example hot pressing, spinning, extrusion, roto-molding or injection molding. Therefore, the present invention additionally relates to the use of the polymer composition according to the invention for the production of a shaped article.

[0318] Depending upon their ultimate end use, the benzocycle-substituted pyrimidines and triazines of the present invention may be combined with a variety of additives conventionally employed in the UV stabilizing art. Examples of such additives include but are not limited to:

[0360] The novel benzocycle-substituted pyrimidines and triazines of the present invention can also be employed in multilayer systems. In such systems, a polymer composition having from about 0.1 to about 20% by weight and preferably a relatively high content of novel stabilizer, for example, about 5-15% by weight, is applied in a thin film (e.g., about 5-500 μm thick and, preferably, about 10-100 μm thick) to a shaped article made from a polymer containing little or no ultraviolet stabilizers. Such composition may be applied at the same time as the shaping of the base structure, for example by coextrusion in a manner analogous to that described in U.S. Pat. No. 4,948,666 (incorporated by reference herein for all purposes as if fully set forth). Alternatively, application can also be made to the ready-formed base structure, for example by lamination with a film or by coating with a solution. The outer layer or layers of the finished article have the function of a UV filter, which protects the interior of the article from UV light. The outer layer preferably contains about 0.1 to about 20%, preferably about 1 to about 15%, and most preferably about 2 to about 10% by weight of the outer layer composition, of at least one of the benzocycle-substituted pyrimidine or triazine compounds of the present invention.

[0361] The polymers stabilized in this way are notable for high weathering resistance, especially for high resistance to UV light. This enables them to retain their mechanical properties, and their color surface properties such as gloss and distinctness of image, for a long time even when used outside. Moreover, due to the bondable nature of the presently claimed triazine compounds, migration of these UV absorbers between the layers of the multi-layer coatings can, under the appropriate circumstances, be minimized.

[0362] In another embodiment of the present invention, the novel mixtures comprising compounds of the formula (I), (II), or (IV)-(IX) can be used as stabilizers for coatings, for example for paints such as disclosed in numerous references (see, e.g., U.S. Pat. No. 4,619,956, U.S. Pat. No. 4,740,542, U.S. Pat. No. 4,826,978, U.S. Pat. No. 4,962,142, U.S. Pat. No. 5,106,891, U.S. Pat. No. 5,198,498, U.S. Pat. No. 5,298,067, U.S. Pat. No. 5,322,868, U.S. Pat. No. 5,354,794, U.S. Pat. No. 5,369,140, U.S. Pat. No. 5,420,204, U.S. Pat. No. 5,461,151, U.S. Pat. No. 5,476,937, EP-0434608 and EP-A-0444323). Of particular interest are coatings and paints for the automobile industry. The invention therefore also relates to those compositions which are film-forming binders for coatings.

[0363] Such novel coating compositions comprise about 0.01 to about 20%, preferably about 0.01 to about 10%, and more preferably about 0.02 to about 5% by weight of the binder of the coating composition of the presently claimed benzocycle-substituted pyrimidines and triazines of the present invention.

[0364] Multilayer systems are possible here as well (such as electrocoat/basecoat/clearcoat systems), where the concentration of the novel stabilizer in one or more of the layers, and typically the outer layer such as the clearcoat, can be relatively high, for example from about 0.01 to about 20%, preferably about 0.01 to about 10%, and more preferably about 0.02 to about 5% by weight of binder.

[0365] The use of the novel stabilizer in coatings is accompanied by the additional advantage that it prevents delamination, i.e. the flaking-off of the coating from the substrate. This advantage is particularly important in the case of metallic substrates, including multilayer systems on metallic substrates, and particularly epoxy e-coated metallic substrates.

[0366] The binder can in principle be any binder which is customary in industry, for example those described in Ullmann's Encyclopedia of Industrial Chemistry, 5th Edition, Vol. A18, pp. 368-426, VCH, Weinheim 1991 which is incorporated herein by reference. In general, it is a film-forming binder based on a thermoplastic or curable resin, predominantly on a curable resin. Examples of thermoplastic binders include acrylics, polyesters, polyurethanes and PVC plastisols. Examples of curable binders include functional alkyd, acrylic, polyester, phenolic, melamine, epoxy and polyurethane resins and mixtures thereof.

[0367] Such curable binders can be an ambient curable or a thermosetting binder. Further, in some systems it may be advantageous to add a curing catalyst to such systems. Suitable catalysts which accelerate curing of the binder are described, for example, in Ullmann's Encyclopedia of Industrial Chemistry, Vol. A18, p. 469, VCH Verlagsgesellschaft, Weinheim 1991. Preferred binders include those which comprise a functional acrylate resin and a crosslinking agent.

[0368] A wide variety of binders may be employed in such coating systems. Examples of suitable coating compositions containing specific binders include but are not limited to:

[0369] 1. paints based on ambient curable or thermosetting alkyd, acrylate, polyester, epoxy or melamine resins or mixtures of such resins, if desired with addition of a curing catalyst;

[0370] 2. two-component polyurethane paints based on hydroxyl-containing acrylate, polyester or polyether resins and aliphatic or aromatic isocyanates, isocyanurates or polyisocyanates;

[0371] 3. one-component polyurethane paints based on blocked isocyanates, isocyanurates or polyisocyanates which are deblocked during baking;

[0372] 4. two-component paints based on (poly)ketimines and aliphatic or aromatic isocyanates, isocyanurates or polyisocyanates;

[0373] 5. two-component paints based on (poly)ketimines and an unsaturated acrylate resin or a polyacetoacetate resin or a methacrylamidoglycolate methyl ester;

[0374] 6. two-component paints based on carboxyl- or amino-containing polyacrylates and polyepoxides;

[0375] 7. two-component paints based on acrylate resins containing anhydride groups and on a polyhydroxy or polyamino component;

[0376] 8. two-component paints based on (poly)oxazolines and acrylate resins containing anhydride groups, or unsaturated acrylate resins, or aliphatic or aromatic isocyanates, isocyanurates or polyisocyanates;

[0377] 9. two-component paints based on unsaturated polyacrylates and polymalonates;

[0378] 10. thermoplastic polyacrylate paints based on thermoplastic acrylate resins or externally crosslinking acrylate resins in combination with etherified melamine resins;

[0379] 11. paint systems based on siloxane-modified or fluorine-modified acrylate resins.

[0380] In addition to the binder and novel benzocycle-substituted pyrimidines and triazines of the present invention, the coating composition according to the invention preferably further comprise one or more additional ultraviolet light absorbers, including but not limited to those specifically listed above in section b. The additional UV absorbers may be, for example, another tris-aryl-1,3,5-triazine, a 2-hydroxyphenyl-2H-benzotriazole, a 2-hydroxybenzophenone, an ester of an unsubstituted benzoic acid, an acrylate, an oxamide (oxanilide), or any combination of the above. Preferably, the additional UV absorber is a 2-hydroxyphenyl-2H-benzotriazole and the weight ratio of benzotriazole to triazine is 4:1 to 1:4. More preferably, the weight ratio is 2:1 to 1:2.

[0381] To achieve maximum light stability, it is of particular interest to add sterically hindered amines, examples of which are set out in the above-mentioned section b(vi). The invention therefore also relates to a coating composition which, in addition to the binder, the novel benzocycle-substituted pyrimidines and triazines and, optionally, additional UV absorbers, comprises a light stabilizer of the sterically hindered amine type. The sterically hindered amine is employed in an amount of about 0.01 to 5% by weight based on the weight of the solid binder, preferably about 0.02 to 2% by weight.

[0382] One specific example of such a sterically hindered amine is a 2,2,6,6-tetramethyl piperazinone containing at least one group of the formula:

[0383] in which J is, for example, hydrogen, hydroxyl, alkyl (such as methyl), alkoxy (such as methoxy) or acyl.

[0384] More preferably the stabilizer is a 2,2,6,6-tetraalkylpiperidine derivative containing at least one group of the formula:

[0385] in which J is, for example, hydrogen, hydroxyl, alkyl (such as methyl), alkoxy (such as methoxy) or acyl.

[0386] Examples of tetraalkylpiperidine derivatives which can be used in combination with the present trisaryl-1,3,5-triazine compounds are given in U.S. Pat. Nos. 4,314,933, 4,344,876, 4,426,471, 4,426,472, 4,619,956, 5,004,770, 5,006,577, 5,064,883, 5,112,890, 5,124,378, 5,106,891, 5,204,473, and 5,461,151, which are incorporated by reference herein for all purposes as if fully set forth. It is particularly expedient to employ the following tetraalkylpiperidine derivatives, as well as their N-alkyl, N-acyl, N-hydroxyl and N-alkoxy analogs (where not already included in the following list): bis(2,2,6,6-tetramethylpiperid-4-yl) succinate, bis(2,2,6,6-tetramethylpiperid-4-yl) sebacate, bis(1,2,2,6,6-pentamethylpiperid-4-yl) sebacate, di(1,2,2,6,6-pentamethylpiperid-4-yl) butyl-(3,5-di-tert-butyl-4-hydroxybenzyl)malonate, bis(1-octyloxy-2,2,6,6-tetramethylpiperid-4-yl) sebacate, tetra(2,2,6,6-tetramethylpiperid-4-yl) butane- 1,2,3,4-tetracarboxylate, tetra(1,2,2,6,6-pentamethylpiperid-4-yl) butane-1,2,3,4-tetracarboxylate, 2,2,4,4-tetramethyl-7-oxa-3,20-diaza-21-oxo-dispiro[5.1.11.2]heneicosane, and 8-acetyl-3-dodecyl-1,3,8-triaza-7,7,9,9-tetramethylspiro[4.5]decane-2,4-dione. Commercially available examples of these and other tetraalkylpipieridine derivatives include SANDUVOR® 3050, 3052, 3055, 3056, 3058, PR-31 and PR-32 (Clariant Corp.); TINUVIN® 079L, 123, 144, 292, 440L and 622LD (Ciba Specialty Chemicals); CHIMASORB® 119 and 944 (Ciba Specialty Chemicals); and CYASORB® UV-3346, UV 3529, UV-3853, UV-500 and UV-516 (Cytec Industries Inc.).

[0387] Apart from the binder, the benzocycle-substituted pyrimidine or triazine, and, if used, the additional ultraviolet light absorber or stabilizer, the coating composition can also comprise further components, examples being solvents, pigments, dyes, plasticizers, stabilizers, thixotropic agents, drying catalysts and/or leveling agents. Examples of possible components are those described in many of the previously incorporated references as well as Ullmann's Encyclopedia of Industrial Chemistry, 5th Edition, Vol. A18, pp. 429-471, VCH, Weinheim 1991; and Calbo, Leonard J., ed., Handbook of Coatings Additives, New York:Marcel Dekker (1987).

[0388] Possible drying catalysts or curing catalysts are, for example, organometallic compounds, amines, acids, amino-containing resins and/or phosphines.

[0389] Examples of acid catalysts are mineral acids, aliphatic and aromatic sulfonic acids (e.g. p-toluene sulfonic acid, dinonylnaphthalene disulfonic acid, dodecylbenzene sulfonic acid), oxalic acid, maleic acid, hexamic acid, phosphoric acid, alkyl phosphate esters, phthalic acid and acrylic acid copolymers.

[0390] Examples of organometallic compounds are metal carboxylates, especially those of the metals Pb, Mn, Co, Zn, Zr or Cu, or metal chelates, especially those of the metal Al, It or Zr, or organometallic compounds such as organotin compounds, for example. Examples of metal carboxylates are the stearates of Pb, Mn or Zn, the octoates of Co, Zn or Cu, the naphthenates of Mn and Co or the corresponding linoleates, resinates or tallates. Examples of metal chelates are the aluminum, titanium or zirconium chelates of acetylacetone, ethyl acetylacetate, salicylaldehyde, salicylaldoxime, o-hydroxyacetophenone or ethyl trifluoroacetylacetate and the alkoxides of these metals. Examples of organotin compounds are dibutyltin oxide, dibutyltin dilaurate or dibutyltin dioctoate.

[0391] Examples of amine drying or curing catalysts are, in particular, tertiary amines, for example tributylamine, triethanolamine, N-methyldiethanolamine, N-dimethylethanolamine, N-ethylmorpholine, N-methylmorpholine or diazabicyclooctane (triethylenediamine) and salts thereof. Further examples are quaternary ammonium salts, for example trimethylbenzylammonium chloride. Amino-containing resins are simultaneously binder and curing catalyst. Examples thereof are amino-containing acrylate copolymers.

[0392] The curing catalyst used can also be a phosphine, for example triphenylphosphine.

[0393] Another type of curing catalyst is a peroxide which can be used, for example, to cure a gel coating for a fiberglass article.

[0394] The novel coating compositions can also be radiation-curable coating compositions. In this case, the binder essentially comprises monomeric or oligomeric compounds containing ethylenically unsaturated bonds, which after application are cured by actinic radiation, i.e. converted into a crosslinked, high molecular weight form. Where the system is UV-curing, it generally contains a photoinitiator as well. Corresponding systems are described in the above-mentioned publication Ullmann's Encyclopedia of Industrial Chemistry, 5th Edition, Vol. A18, pages 451-453. In radiation-curable coating compositions, the novel stabilizers can also be employed without the addition of sterically hindered amines.

[0395] The novel coating compositions according to the invention can be applied to any desired substrates, for example to metal, wood, plastic, fiberglass or ceramic materials. The coating compositions can be pigmented mono-coats or multi-layer (primer/basecoat/clearcoat) systems typical of automotive finishes. In the latter case, the novel coating composition can be used for either the base coat, or clear coat, or for both layers. If the topcoat of an automotive finish comprises two layers, of which the lower layer is pigmented and the upper layer is not pigmented, the novel coating composition can be used for either the upper or the lower layer or for both layers, but preferably for the upper topcoat layer.

[0396] The novel coating compositions can be applied to the substrates by the customary methods, for example by brushing, spraying, pouring, dipping or electrophoresis; see also Ullmann's Encyclopedia of Industrial Chemistry, 5th Edition, Vol. A18, pp. 491-500.

[0397] Depending on the binder system, the coatings can be cured at room temperature or by heating. Thermosetting coatings are preferably cured at 50-150° C. and, in the case of powder coatings, even at higher temperatures.

[0398] The coatings obtained in accordance with the invention have excellent resistance to the damaging effects of light, oxygen and heat; particular mention should be made of the good light stability and weathering resistance of the coatings thus obtained, for example paints.

[0399] The invention therefore also relates to a coating, in particular a paint, which has been stabilized against the damaging effects of light, oxygen and heat by a content of the compound of the formula (I), (II), or (IV)-(IX), according to the invention. The paint can be a pigmented mono-coat which comprises a film-forming binder and an organic pigment or dye, an inorganic pigment, a metallic pigment, or a mixture thereof. The paint may also be a composition which comprises a primer in adhesion to a metal or plastic substrate; a pigmented basecoat that is in adhesion to the primer and which comprises a film-forming binder and an organic pigment or dye, an inorganic pigment, a metallic pigment, or a mixture thereof; and a clear coat that is in adhesion to the base coat and which comprises a film-forming binder and optionally a transparent pigment. One especially preferred use is a paint which is a clear topcoat for automobile original equipment manufacture (OEM) and/or refinish applications.

[0400] The invention furthermore relates to a process for stabilizing a coating based on polymers against damage by light, oxygen and/or heat, which comprises mixing with the coating composition a mixture comprising a compound of a benzocycle-substituted pyrimidine or triazine and to the use of mixtures comprising benzocycle-substituted pyrimidine or triazine compound in coating compositions as stabilizers against damage by light, oxygen and/or heat.

[0401] The coating compositions can comprise an organic solvent or solvent mixture in which the binder is soluble. The coating composition can otherwise be an aqueous solution or dispersion. The vehicle can also be a mixture of organic solvent and water. The coating composition maybe a high-solids paint or can be solvent-free (e.g. a powder coating material).

[0402] The pigments can be inorganic, organic or metallic pigments. The novel coating compositions preferably contain no pigments and are used as a clearcoat.

[0403] Likewise preferred is the use of the coating composition as a topcoat for applications in the automobile industry, especially as a pigmented or unpigmented topcoat of the paint finish. Its use for underlying coats, however, is also possible.

[0404] The benzocycle-substituted pyrimidine or triazines of this invention may be applied topically by polishing a surface with a composition comprising the benzocycle-substituted pyrimidine or triazines and an inert carrier such as solvent, petroleum jelly, silicone oil in water emulsions, or automotive paint wax, e.g. Carnauba wax. These topical treatment compositions may be used to stabilize coating films, fabrics, leather, vinyl and other plastics and wood.

[0405] Preference is also given to the use of the novel benzocycle-substituted pyrimidine or triazine compounds in photographic materials as stabilizer against damage by light, especially by UV light. The invention therefore also relates to a photographic material comprising an benzocycle-substituted pyrimidine or triazine compound.

[0406] The compounds according to the invention can be used for photosensitive materials of all kinds. For example, they can be employed for color paper, color reversal paper, direct-positive color material, color negative film, color positive film, color reversal film and other materials. They are preferably used, inter alia, for photosensitive color material which comprises a reversal substrate or which forms positives.

[0407] Furthermore, the novel compounds can be combined with other UV absorbers, especially those which are dispersible in aqueous gelatin, for example with hydroxyphenylbenzotriazoles (cf. for example U.S. Pat. Nos. 4,853,471, 4,973,702, 4,921,966 and 4,973,701), benzophenones, oxanilides, cyanoacrylates, salicylates, or acrylonitriles or thiazolines. In this context it is advantageous to employ these further, oil-dissolved UV absorbers in the photographic material in layers other than those comprising the novel UV absorbers.

[0408] The present invention also encompasses compositions containing one or more binders. In particular, the binder may comprise an alkyd, acrylic, polyester, phenolic, melamine, epoxy or polyurethane resin, or blends thereof. Examples of such binders include, but are not limited to:

[0409] (a) cold- or hot-crosslinkable alkyd, acrylate, polyester, epoxy or melamine resins or mixtures of such resins;

[0410] (b) a two-component polyurethane system comprising hydroxyl-containing acrylate, polyester or polyether resins and aliphatic or aromatic isocyanates, isocyanurates or polyisocyanates;

[0411] (c) a one-component polyurethane system comprising blocked isocyanates, isocyanurates or polyisocyanates which are deblocked during baking;

[0412] (d) a two-component system comprising (poly)ketimines and aliphatic or aromatic isocyanates, isocyanurates or polyisocyanates;

[0413] (e) a two-component system comprising (poly)ketimines and an unsaturated acrylate resin or a polyacetoacetate resin or a methacrylamidoglycolate methyl ester;

[0414] (f) a two-component system comprising carboxyl- or amino-containing polyacrylates and polyepoxides;

[0415] (g) a two-component system comprising acrylate resins containing anhydride groups and on a polyhydroxy or polyamino component;

[0416] (h) a two-component system comprising (poly)oxazolines and acrylate resins containing anhydride groups, or unsaturated acrylate resins, or aliphatic or aromatic isocyanates, isocyanurates or polyisocyanates;

[0417] (i) a two-component system comprising unsaturated polyacrylates and polymalonates;

[0418] (j) a thermoplastic polyacrylate system comprising thermoplastic acrylate resins or externally crosslinking acrylate resins in combination with etherified melamine resins; and

[0419] (k) a system comprising siloxane-modified or fluorine-modified acrylate resins.

[0420] Such binder-containing compositions may further comprise a curing catalyst, or an organic solvent, and may be radiation-curable. In particular, such compositions may serve as coating compositions.

[0421] In particular, it is possible successfully to stabilize photographic materials similar to those described in U.S. Pat. No. 4,518,686.

[0422] The invention therefore additionally relates to a photographic material comprising, on support, a blue-sensitive, a green-sensitive and/or a red-sensitive silver-halide emulsion layer and, if desired, a protective layer, with a layer comprising a UV absorber being arranged above the uppermost silver-halide emulsion layer, wherein the UV absorber is a benzocycle-substituted pyrimidine or triazine compound.

[0423] Preference is additionally given to photographic materials which have a layer comprising a compound of the formula (I), (II), or (IV)-(IX) above the uppermost silver-halide emulsion layer and/or between the green- and red-sensitive silver-halide emulsion layers.

[0424] Furthermore, it may be advantageous for all or some of the said layers which can comprise a UV absorber to have a UV absorber mixture and/or a further UV absorber which is dispersible in aqueous gelatin, but a compound of the formula (I), (II), or (IV)-(IX) must be present at least in one layer.

[0425] The novel material preferably has gelatin interlayers between the silver-halide emulsion layers.

[0426] Preference is given to photographic materials in which the silver halide in the blue-sensitive, green-sensitive and/or red-sensitive layer is silver chloride bromide comprising at least 90 mol % of silver chloride.

[0427] The compounds of the formula (I), (II), or (IV)-(IX), which are used in accordance with the invention, can be incorporated, alone or together with the color coupler and, if used, further additives, into the color photographic materials by dissolving the compounds beforehand in high-boiling organic solvents. It is preferred to use solvents which boil at higher than 160° C. Typical examples of such solvents are the esters of phthalic acid, phosphoric acid, citric acid, benzoic acid or of fatty acids, or alkylamides and phenols.

[0428] Preferred color couplers for use in the compositions of the invention, examples of such compounds, further additives such as color cast inhibitors, DIR couplers and further light stabilizers, such as UV absorbers, phenols, phosphorus (III) compounds, organometallic complexes, hydroquinones and hydroquinone ethers, and more precise details on the structure of various photographic materials, can be found, for example, in the publications EP-A-0531258 and EP-A-0520938 and in the literature cited therein.

FILM

[0429] The invention also relates to a process for the stabilization of polyolefin or polyolefin copolymer films for agricultural applications, especially greenhouse applications, this polyolefin or polyolefin copolymer film having improved light stability and pesticide resistance, comprising incorporation of at least one benzocycle-substituted pyrimidine or triazine UV absorbers of the present invention, sterically hindered amines and metal oxides of hydroxides selected from the oxides of zinc, aluminum, calcium, and magnesium and hydroxides of zinc, aluminum, and calcium into the polyolefin or polyolefin copolymer.

[0430] A further subject of the invention is a greenhouse, characterized in that it is covered by a polyolefin or polyolefin copolymer film having improved light stability and pesticide resistance and stabilized with a at least one benzocycle-substituted pyrimidine or triazine UV absorbers of the present invention, sterically hindered amines and metal oxides of hydroxides selected from the oxides of zinc, aluminum, calcium, and magnesium and hydroxides of zinc, aluminum, and calcium.

[0431] Another subject of the invention is a process for stabilizing a polyolefin or polyolefin copolymer greenhouse film against detrimental effects of pesticides and light, oxygen and/or heat, which process comprises incorporation of at least one benzocycle-substituted pyrimidine or triazine UV absorbers of the present invention, sterically hindered amines and metal oxides of hydroxides selected from the oxides of zinc, aluminum, calcium, and magnesium and hydroxides of zinc, aluminum, and calcium into said greenhouse film.

[0432] Further subjects of the invention are the use of a polyolefin copolymer film stabilized with at least one benzocycle-substituted pyrimidine or triazine UV absorbers of the present invention, sterically hindered amines and metal oxides of hydroxides selected from the oxides of zinc, aluminum, calcium, and magnesium and hydroxides of zinc, aluminum, and calcium for the stabilization of polyolefin or polyolefin copolymer films in contact with pesticides against photodegradation and damage by pesticides.

[0433] To form a film, forcing a quantity of the said melted composition through a film die, such as a flat film die or a circular blown film die, and forming a film therefrom. In the case where the composition is used to form a film therefrom, it is contemplated that the films may be unoriented, or may be subjected to a conventional operation to impart a degree of orientation on the film. Such a film may be oriented in one direction, such as in the machine direction, such as in the “machine direction” and/or the “transverse direction”, or may be oriented in both directions, or “biaxially” oriented.

[0434] The present invention is also suitable for sheet applications.

[0435] The benzocycle-substituted pyrimidine or triazine compounds of the formula (I), (II), or (IV)-(IX) are suitable for the photochemical stabilization of undyed, dyed or printed fiber materials comprising for example, silk, leather, wool, polyamide or polyurethanes and especially cellulose-containing fiber materials of all kinds. Examples of such fiber materials are the natural cellulose fibers, such as cotton, linen, jute and hemp and also viscose staple fiber and regenerated cellulose. Preferred textile fiber materials are those of cotton. The triazine and pyrimidine compounds of the present invention are also suitable for the photochemical stabilization of hydroxyl-containing fibers in blend fabrics, for example blends of cotton with polyester fibers or polyamide fibers. A further preferred area of application relates to the blocking or reduction of the UV radiation which passes through the above-mentioned textile materials (UV cutting) and the heightened sun protection which textile materials finished with a novel compound offer to the human skin.

[0436] To this end, one or a number of different compounds of the formula (I), (II), or (IV)-(IX) are applied to the textile fiber material by one of the customary dyeing methods, advantageously in a quantity of 0.01 to 5% by weight, preferably 0.1 to 3% by weight and, in particular, from 0.25 to 2% by weight, based on the weight of the fiber material.

[0437] The benzocycle-substituted pyrimidine or triazine compounds can be applied to the fiber material in various ways and fixed on the fiber, especially in the form of aqueous dispersions or printing pastes.

[0438] The textile fiber materials finished with the novel compounds of the formula (I), (II), or (IV)-(IX) possess improved protection against photochemical breakdown of the fiber and yellowing phenomena and, in the case of dyed fibre material, are of enhanced (hot) light fastness. Particular emphasis should be drawn to the greatly improved photoprotective effect of the treated textile fiber material and, in particular, the good protective effect with respect to short-wave UV-B rays. This is manifested by the fact that the textile fiber material finished with an benzocycle-substituted pyrimidine or triazine compound has, relative to untreated fabric, a greatly increased sun protection factor (SPF).

[0439] The sun protection factor is defined as the quotient of the dose of UV radiation which damages protected skin to that which damages unprotected skin. Accordingly, a sun protection factor is also a measure of the extent to which untreated fiber materials and fiber materials treated with a novel compound of the formula (I), (II), or (IV)-(IX) are permeable to UV radiation. The determination of the sun protection factor of textile fiber materials is explained, for example, in WO94/04515 or in J. Soc. Cosmet. Chem. 40, 127-133 (1989) and can be carried out analogously thereto.

[0440] Yet another use of the UV absorbers according to the invention is in the stabilization of intra-ocular and contact lenses.

[0441] The inventive UV absorbers are suitable as photoprotective agents in cosmetic preparations. The invention additionally relates, therefore, to a cosmetic preparation comprising at least one benzocycle-substituted pyrimidine or triazine compound and cosmetically acceptable carriers or auxiliaries.

[0442] The novel cosmetic composition contains from 0.1 to 15% by weight, preferably from 0.5 to 10% by weight, based on the overall weight of the composition, of a benzocycle-substituted pyrimidine or triazine UV absorber and a cosmetically acceptable auxiliary.

[0443] The cosmetic composition can be prepared by physically mixing the novel UV absorber with the auxiliary by means of customary methods, for example by simply stirring together the two materials.

[0444] The cosmetic preparation according to the invention can be formulated as a water-in-oil or oil-in-water emulsion, as an oil-in-oil alcohol lotion, as a vesicular dispersion of an ionic or nonionic amphiphilic lipid, as a gel, solid stick or as an aerosol formulation.

[0445] As a water-in-oil or oil-in-water emulsion, the cosmetically acceptable auxiliary preferably contains from 5 to 50% of an oily phase, from 5 to 20% of an emulsifier and from 30 to 90% water. The oil phase can comprise any oil which is suitable for cosmetic formulations, e.g., one or more hydrocarbon oils, a wax, a natural oil, a silicone oil, a fatty acid ester or a fatty alcohol. Preferred mono- or polyols are ethanol, isopropanol, propylene glycol, hexylene glycol, glycerol and sorbitol.

[0446] For these cosmetic formulations, it is possible to use any conventionally employed emulsifier, e.g., one or more ethoxylated esters of naturally occurring derivatives, i.e., polyethoxylated esters of hydrogenated castor oil; or a silicone oil emulsifier such as silicone polyol; an unmodified or ethoxylated fatty acid soap; an ethoxylated fatty alcohol; an unmodified or ethoxylated sorbitan ester; an ethoxylated fatty acid; or an ethoxylated glyceride.

[0447] The cosmetic formulation can also comprise further components, for example emollients, emulsion stabilizers, skin moisteners, tanning accelerators, thickeners such as xanthan, moisture retention agents such as glycerol, preservatives, or fragrances and colorants.

[0448] The novel cosmetic formulations are notable for good protection of human skin against the damaging effect of sunlight while at the same time providing for reliable tanning of the skin.

[0449] The invention will now be illustrated by the following examples. The examples are not intended to be limiting of the scope of the present invention. In conjunction with the general and detailed descriptions above, the examples provide further understanding of the present invention.

EXAMPLES

[0450] Examples and reaction schemes for producing specific examples of benzocycle substituted triazines in accordance with the invention are provided below. While the following examples illustrate preparations with one or more tetralin benzocyles, one of ordinary skill will understand that these reactions may also be carried out with any of a variety of other benzocycles, where when necessary, reactive substituents on such other benzocycles are protected in accordance with procedures and reagents well known and understood by those of ordinary skill.

PREPARATIVE EXAMPLES Example 1: Reaction of Cyanuric Chloride with Tetralin: Use of Tetralin as Solvent

[0451]

[0452] To a reaction flask equipped with a reflux condenser, an argon inlet, a magnetic stirring bar and a glass stopper was added 100 mL of tetralin and 9.2 g of cyanuric chloride. To the resulting solution was added 10 g of anhydrous AlCl₃ over a period of 10 minutes at 0° C. After the addition was over, the reaction mixture was heated in an oil bath at 40° C. for 16 hours. The heating was discontinued and the reaction mixture was cooled in an ice bath and treated with ice-cold water. The reaction mixture was then extracted with methylene chloride and the organic layer dried over anhydrous sodium sulfate and concentrated to remove volatiles. The residue was treated with methanol affording a precipitate which was filtered, washed with methanol and dried to give 12.4 g of the product. The NMR and mass analysis of the product showed it to consist of a mixture of monotetralin-bischloro-triazine (Compound A), bistetralin-monochloro-triazine (Compound B) and tristetralin-triazine (Compound C).

Example 1 Alternate Procedure: Use of Monochlorobenzene as Solvent

[0453] A mixture of 47.7 g (0.256 mole) of cyanuric chloride and 67.6 g (0.507 mol) of aluminum chloride in 360 mL of chlorobenzene under nitrogen was heated to 40° C. Tetralin (68 mL, 0.500 mole) was added over the course of two hr. During this time the temperature increased to 50° C. The temperature was maintained at 50° C. until an exotherm occurred.

[0454] After the exotherm had subsided, 200 mL of 10% aqueous HCl was added drop-wise such that the temperature was maintained below 50° C. The resulting mixture was filtered. The aqueous layer from the filtrate was extracted with methylene chloride. The combined organic layers were washed with water, dried over anhydrous magnesium sulfate, and treated with activated carbon. After filtration, the filtrate was concentrated in vacuo. The residue was taken up in 300 mL of tetrahydrofuran, and cooled to 0° C. The precipitate was removed by filtration. The filtrate was concentrated in vacuo to give an oil which slowly crystallized to a dark yellow to brown solid, which contained P-4036 (50-70 area % by HPLC) plus tris-tetralin triazine and unreacted cyanuric chloride.

Example 2: Bistetralin-monoresorcinol-triazine (Compound D)

[0455]

[0456] A mixture of 132.3 g of the product of Example I Alternate Procedure (Compound B) and 38.7 g of resorcinol in 300 mL of chlorobenzene was heated to 60° C. Aluminum chloride (61.0 g) was added over a 2 hr. during which time the temperature increased to 80° C. The mixture has held at 80° C. for an additional 2 hr.

[0457] After cooling to 60° C., the reaction mixture was poured into 400 mL of ice water. The mixture was concentrated in vacuo. The residue was triturated with 400 mL of water, and the resulting slurry was filtered. The solid was air-dried and then dried in vacuo. A Soxhlet extraction of the solid was done with refluxing chloroform. A solid precipitated from the chloroform extract. The solid was filtered, washed with cold chloroform, and dried to give Compound D as a light yellow powder in >92% purity by HPLC.

Example 2 Alternate Procedure

[0458] To a stirred suspension of 40 g cyanuric chloride in 544 mL chlorobenzene maintained at ice bath temperature under nitrogen was added 87 g of aluminum chloride. Concentrated hydrochloric acid (4.34 mL) was added over 10 min during which the reaction temperature was kept below 5° C. The reaction mixture was stirred at between about 0° C. to about 5° C. for an additional 10 min, and then cooled to −10° C. Tetralin (56 mL) was added at −10° C. over 2 hr. The reaction mixture was then stirred at −10° C. for 2 hr, warmed to 0° C., and stirred for 1 hr.

[0459] The reaction mixture was heated to 40° C. and 26.3 g of resorcinol was added over 10 min. The mixture was heated to 80° C. and stirred for 2 hr. Compound D was isolated according to the procedure of Example 3.

Example 3: Bistetralin-(monoresorcinol-4-O-octyl)-triazine Derivative (Compound E)

[0460]

[0461] A mixture of 400 mg of the product of Example 2 (Compound D), 1.38 g of anhydrous potassium carbonate, 0.2 mL of 1-iodooctane and 10 mL of acetone was heated to reflux for 24 hours. The reaction mixture was then cooled to room temperature and diluted with methylene chloride. The resulting mixture was filtered through Celite, and concentrated to dryness to give 422 mg of a crude product. The crude product was purified by column chromatography over silica gel to give a pure compound which was identified to be the bistetralin-(monoresorcinol-4-O-octyl)-triazine derivative (Compound E) by NMR and mass spectra.

Example 4: Monotetralin-bischloro-triazine (Compound F)

[0462]

[0463] A 3-necked, one liter flask was charged with 48 g of anhydrous aluminum chloride, 56.11 g of cyanuric chloride and 240 mL of chlorobenzene. The apparatus was purged with nitrogen and the mixture was heated to 65° C.

[0464] Neat tetralin (60 mL) was added dropwise to the solution at a constant rate of about 1.3 mL per minute such that all the tetralin was added in 45 minutes. The temperature was maintained between 63 and 68° C. during this period. As the addition of tetralin proceeded, the solution became red-black in color. After the addition was complete, the temperature was maintained at 65-70° C. for an additional 60 min. The mixture was then allowed to cool to about 50° C.

[0465] A mixture of 20 mL of concentrated aqueous HCl and 180 mL of water was added through the dropping funnel. During the addition the mixture was cooled with an ice bath. The aqueous acid was added dropwise at least keeping the temperature between 45 and 50° C., and then more rapidly as the exothermic reaction lessened. The entire mixture was diluted with 300 mL of methylene chloride, and the aqueous layer was removed. The organic layer was washed twice with water and then dried over anhydrous magnesium sulfate.

[0466] The dried organic mixture was then filtered to remove magnesium sulfate and concentrated on a rotary evaporator. After cooling, about 300 mL of hexanes was added giving a white precipitate. This was filtered and washed with hexanes to give, after drying in vacuo, the desired product (Compound F) in 96% purity by HPLC analysis.

Example 5: Monotetralin-bisresorcinol-triazine (Compound G)

[0467]

[0468] To a 3-necked 250-mL round bottomed flask was charged with 14.0 g of monotetralin-bischloro-triazine (Compound F), 11.56 g of resorcinol, and 130 mL of chlorobenzene and then purged with nitrogen. Into the solids addition funnel was placed 18.76 g of anhydrous aluminum chloride. The solution was heated to 49° C. and addition of aluminum chloride was begun in portions. The aluminum chloride was added over the course of two hours and the temperature allowed to slowly climb to 65° C. The reaction mixture was then heated to 90-95° C. and held in that range for 3 hours. The mixture was a dark red slurry at this point.

[0469] At the end of the reaction period, the heat was removed and the temperature allowed to fall to about 60° C. The attachments were then removed from the reaction flask and the mixture was poured into 200 mL of cold water. The mixture was shaken, discharging the red color and leaving a yellow emulsion. When this had cooled completely, it was transferred to a round bottomed task and the chlorobenzene-water azeotrope was removed on a rotary evaporator until no further chlorobenzene was observed in the condensate. The resultant light yellow slurry was filtered, washed with water and dried in vacuo to give the desired product (Compound G).

GE Lexan 105 barefoot natural flake polycarbonate resin (melt temperature 310-333° C.) was dry blended with 0.35% stabilizer plus 0.10 wt % Mark® 2112 phosphite. The blended compositions were melt-mixed and extruded in a Haake torque rheometer equipped with a a 0.75-inch 25:1 single mixing screw extruder. The zone temperatures were 246, 265, 295, and 304° C. The extruded polycarbonate was pulled through a water bath, dried, pelletized, and redried at 120° C. for 4-48 hr in a forced air oven. The pellets were injection molded at 340° C. with a 40 second dwell time using an Arburg “Allrounder” hydraulic injection molder to form 2×2.5×0.100-inch plaques. The mold temperature was 100° C. The injection barrel temperature of 340° C. was selected to simulate extremely harsh conditions. Yellow indices and delta E data were obtained using a Macbeth Color Eye Colorimeter with illuminate C, 2° observer, specular component excluded, and UV component included. As can be seen from Table III, Compound E is more resistant to thermal yellowing than Tinuvin 1577, a current art triazine UV absorber.
